AIR SEPARATION SYSTEM, METHOD FOR CRYOGENIC DECOMPOSITION OF AIR USING AIR SEPARATION SYSTEM AND METHOD FOR CREATING AN AIR SEPARATION SYSTEM

摘要

The invention relates to an air separation plant (100) with four separation units (1-4) in the form of a high-pressure column (1), a foot section (2) of a two-part low-pressure column, a head section (3) of the two-part low-pressure column and a one-part argon recovery column (4 ) with a top capacitor (41), the separation units (1-4) being connected at least in part by means of lines (5) to one another and / or to one or more further apparatuses (6-8), the separation units (1-4 ) each have longitudinal axes (A) which run in the direction of maximum extension of the separating units (4), the separating units (4) being arranged such that their longitudinal axes (A) lie parallel to one another, and the lines (5) at least partially Have line sections that run parallel to the longitudinal axes of the separation units (1-4). It is provided that at least the majority of the line sections of the lines (5) running parallel to the longitudinal axes (A) of the separation units (1-4) are arranged in a compartment (C), and that the compartment (C) and the separation units (1-4) in a projection onto a plan plane, which is perpendicular to the longitudinal axes of the separating units (1-4), are arranged in four quadrants (Q1-Q4) such that in a first (Q1) of the quadrants (Q1-Q4 ) at least the major part of the high pressure column (1) and the foot section (2) of the two-part low pressure column one above the other, in a second (Q2) of the quadrants (Q1-Q4) at least the major part of the head section (3) of the low pressure column, in a third (Q3) of the quadrants (Q1-Q4) at least the major part of the argon extraction column (4) and in a fourth (Q4) of the four quadrants (Q1-Q4) the compartment (C) are arranged. A corresponding method for the low-temperature separation of air and a method for creating a corresponding air separation plant (100) are also the subject of the invention.
